SXT2148DA48-27.120M

Crystals Overview

The SXT2148DA48-27.120M is a surface-mount ceramic crystal oscillator manufactured by Suntsu Electronics, Inc., operating at a nominal frequency of 27.12 MHz. It features a 4-SMD, no-lead package with dimensions of 2.0 x 1.6 mm. The component exhibits a frequency tolerance of ±20 ppm and a frequency stability of ±20 ppm over the operating temperature range of -40°C to +85°C. It utilizes an 8 pF load capacitance and has a maximum equivalent series resistance (ESR) of 100 Ohms. Designed for base harmonic operation, it supports a typical drive level of 50 μW.

Crystals Feature Summary

• Compact 2.0 x 1.6 mm four-pad surface mount footprint suitable for space-constrained designs
• High frequency stability of ±20 ppm across industrial temperature ranges
• Robust low-temperature performance with reliable oscillation start-up below -40°C
• Low equivalent series resistance ensuring efficient power consumption

Crystals Applications

• Portable Bluetooth audio devices requiring precise clocking
• Small communication modules with strict size limitations
• SSD secondary boards needing compact timing solutions
• Wearable electronic devices prioritizing low power usage

Crystals Procurement Notes

Verify the specific suffix DA48 confirms the ±20 ppm tolerance and -40°C to +85°C temperature range against the official datasheet. Ensure the 8 pF load capacitance matches the target circuit design requirements. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference the 4-SMD no-lead package dimensions with PCB footprints to prevent mounting errors during production.

Crystals Selection Notes

Select this component when a 27.12 MHz signal is required within a 2.0 x 1.6 mm envelope. Choose based on the need for ±20 ppm stability in industrial environments rather than commercial grades. Consider the 100 Ohm ESR limit for oscillator circuit compatibility. Evaluate the 50 μW drive level against the host controller's output capability to ensure stable operation without overdriving the crystal.

Crystals Part Context

This part belongs to the SXT214 series of ceramic surface-mount crystals from Suntsu Electronics. The series offers various load capacitances and tolerance grades, including ±10 ppm and ±50 ppm options. The 2148 designation indicates the specific package style and thermal characteristics, distinguishing it from other series like SXT2141 or SXT21418 which may differ in size or electrical specifications.

Crystals Replacement Considerations

Direct substitutes include other SXT2148DA48 variants with different frequencies, such as SXT2148DA48-30.000M, provided the frequency change is acceptable. Alternative models within the same series with different tolerances, like SXT2148CA16-27.120M, may fit mechanically but require verification of stability and temperature range differences.
